I had to smile at the article on science and gender (perhaps in order not to cry?) ("Sisters' winning formula", 30 September).

I was a physics major in the US about 25 years ago. In my second year, my quantum physics course was taught by a professor from the University of Oxford. I was one of a handful of females in the class and had to this point encountered no real issues. He handed back our exam papers and I had, as was often the case, achieved the highest mark. He had no comment until later when, at an end-of-term party, he informed me that women should not go into physics - it was too difficult a subject for them.

In the end, I did switch to cognitive science, because its wider knowledge base of subjects was more interesting to me and it had a much better gender balance.

I am afraid now, having read the article, that I am one of those women who believes, perhaps to my detriment, that diversity in research indicates intellectual challenge and scholarly breadth. Having gained an MSc and a PhD from Carnegie Mellon University, I worked in industrial research laboratories and in departments of psychology, computer science and informatics in the US and the UK.

I came to a new medical school in 2003 excited about the prospects of applying my knowledge to a new curriculum and pursuing interdisciplinary research with colleagues from many disciplines. I have found several strikes against me, none of them related to my ability. I am a non-male, a non-medic and not in biomedical research. Even my title suggests that I am somehow deficient. Also, academic medicine, contrary to the opinion of John Radford (Letters, 7 October), is dominated by males; in 2005, only 10 per cent of professors in the UK were female.

I feel that my career has stagnated somewhat, at least for now, and while I have some truly wonderful colleagues, it seems that many have little respect for what I do.

Having spoken to social science colleagues in many other medical schools, I know that my experiences are far from unique. While the article mainly discussed the natural sciences, there are similar barriers for women in other disciplines as well.
